Abstract
Disclosed is a stud bolt having nonsymmetrical screw threads projecting from the shank thereof, wherein each screw thread of the stud bolt has an inwardly concave curved flank and an outwardly convex curved flank. With this arrangement, the load required to fit a resin clip over the stud bolt can be lowered below that needed for a conventional stud bolt while maintaining the load required to remove the clip equal to or more than that for the conventional bolt. Thus, this stud bolt allows a resin clip to be easily fitted over the bolt.
